Gallium Nitride Displaces Silicon in Infrastructure Amplifiers
5G base station manufacturers are specifying gallium nitride power amplifiers over legacy LDMOS silicon designs for new small cell and massive MIMO deployments, a transition driven by gallium nitride's higher efficiency at the higher frequency bands 5G requires. Several major infrastructure OEMs have shifted the majority of new base station designs to gallium nitride amplifiers over the past three years, and more than 70 percent of new 5G massive MIMO deployments in 2025 used gallium nitride devices rather than silicon alternatives. This shift pushes silicon-focused suppliers to requalify product lines or cede share in the fastest-growing segment.
